FS#7308 - Noise Cancelling
Hi all
New to Rockbox so apologies if this has already been considered/discussed…
Thought it might be useful to implement a noise cancelling feature using the inbuilt mic (or line in mic come to think of it), negating the input and playing back with music or radio. Then I wouldn’t need to spend a fortune on noise cancelling headphones which work the same way.
“Noise Cancelling” menu options might be “On/Off”, “Input Source” and “Sensitivity” so you can adjust the level of noise that is cancelled - I’ve often thought if there was a bus blasting it’s horn at me to get out of the way or a fire alarm going off I might not want these cancelled!
Many thanks
Rod

Active noise cancellation generally requires you to measure the incident sound wave at the transducer. I don’t think your idea would work.
Also, if you want noise isolation, you can get very good results using a <$30 pair of internal ear headphones.
